Description

Technical Field

[0001] This utility model relates to the field of accumulator technology, and in particular to an easily replaceable accumulator for hydraulic stations. Background Technology

[0002] Hydraulic transmission technology, with its advantages of high power density, smooth transmission, and precise control, is widely used in many industrial fields such as metallurgy, mining, engineering machinery, plastic injection, and aerospace. As the core power source of the hydraulic system, the stability and reliability of the hydraulic power station directly affect the normal operation of the entire equipment or production line. In the hydraulic power station, the accumulator is a crucial auxiliary component. It achieves multiple functions such as energy storage, release, absorption of pressure pulsation, and serving as an emergency power source by isolating the internal compressible gas (usually nitrogen) from the incompressible hydraulic oil. An accumulator with publication number CN215333688U is characterized by comprising a top cover, an outer cylinder of the accumulator, a bottom cover, and an inflation valve; the top cover is fixed to the top of the outer cylinder of the accumulator; the bottom cover is fixed to the lower end of the outer cylinder of the accumulator; the inflation valve is located on one side of the lower part of the outer cylinder of the accumulator, and the lowest liquid level in the accumulator is higher than the position of the inflation valve. This accumulator effectively overcomes the above-mentioned shortcomings, providing the same function as a standard accumulator while having the advantages of small size, light weight, and low cost. It employs a liquid-sealed gas method to prevent nitrogen leakage from the accumulator. In the operation of hydraulic systems, the core components of accumulators (such as air bladders, diaphragms, and seals) are prone to aging and failure due to long-term high pressure, temperature fluctuations, or media corrosion, which in turn affects the safety of use. The existing technology mentioned above uses liquid-sealed gas to prevent nitrogen leakage from the accumulator, but it is inconvenient to disassemble the accumulator easily, making it difficult to repair in time when the accumulator leaks accidentally, thus affecting the safety of use. Therefore, corresponding improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to provide a hydraulic accumulator that can be easily replaced, so as to solve the problem mentioned in the background art that the existing hydraulic accumulators are inconvenient to disassemble, inspect and maintain during use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an easily replaceable accumulator for a hydraulic station, comprising an accumulator body, an inlet pipe, and a pressure relief pipe, wherein the bottom end of the accumulator body is connected to the inlet pipe, and the outside of the inlet pipe is connected to the pressure relief pipe; The bottom end of the inlet pipe is connected to a fixed plate, and the bottom end of the fixed plate is fitted with a mating plate. The bottom end of the mating plate is connected to a connecting pipe. A fixing component is provided between the fixed plate and the mating plate. The bottom end of the connecting pipe is connected to a high-pressure ball valve, and the bottom end of the high-pressure ball valve is connected to a connecting pipe.

[0005] Furthermore, the fixing component includes plug-in posts connected to both sides of the bottom end of the fixing plate, and each plug-in post is fixed with a locking screw at its bottom end, and the locking screw is threadedly connected to a threaded sleeve on its outer side.

[0006] Furthermore, positioning holes are provided on both sides of the inner surface of the docking plate, and locking holes are provided on both inner walls of the positioning holes.

[0007] Furthermore, one end of each of the plug-in pins passes through the positioning hole, and both sides of each plug-in pin are connected to a locking protrusion, which engages with the locking hole.

[0008] Furthermore, both sides of the bottom end of the fixed plate are evenly connected with sealing protrusions, and both sides of the top end of the docking plate are evenly provided with sealing grooves, which are interlocked with the sealing protrusions.

[0009] Furthermore, a sealing sleeve is fitted onto the outer side of the pressure relief pipe, and threaded grooves are evenly arranged on the inner wall of the sealing sleeve. The pressure relief pipe is threadedly connected to the sealing sleeve, and a flow diversion component is provided inside the pressure relief pipe.

[0010] Furthermore, the diversion assembly includes a diversion plate threadedly connected to the inside of the pressure relief pipe, and the diversion plate is evenly provided with diversion holes, and a rotating frame is connected to one side of the diversion plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the easily replaceable accumulator for the hydraulic station can be easily disassembled in case of accidental leakage, making it flexible and convenient to use; When the accumulator body leaks unexpectedly, close the high-pressure ball valve to block the oil from the main hydraulic system line, completely isolating the accumulator body and inlet pipe from the high-pressure main system. Then, depressurize the inlet pipe to easily disassemble the accumulator body and high-pressure ball valve. By screwing the threaded sleeve, disengage it from the locking screw. Then, pull the fixing plate to disengage the snap-fit ​​protrusion from the locking hole until the plug-in post disengages from the positioning hole. This allows the fixing plate and the docking plate to be separated, facilitating the easy replacement of the accumulator body for maintenance and reducing usage risks. During the depressurization process, select the sealing sleeve and unscrew it from the depressurization pipe to safely release the high-pressure oil and gas remaining in the pipe and accumulator body into the oil tank or mobile device, so as to avoid the residual high-pressure oil spraying out directly and causing serious injury and equipment damage. During the pressure relief process, the use of a flow divider plate and multiple flow dividers achieves a flow diversion effect, reducing the flow velocity and impact force of the outflowing oil, transforming the violent jetting into a smooth flow, and improving the safety of pressure relief.
